Today I brought it up on the variac for the first time and monitored the voltages. At 117VAC line voltage the filaments were 6.28V and the B+ was 392 VDC, right on the money per the schematic. It's been running about 4 or 5 hours and the giant power supply transformer is just slightly warm. Seems like this thing is over built at about 40 Watts. I decided to not replace the two tall 4 uF 600V e-caps, I think they are the sealed liquid type and seen fine. Why the heck does it have those 600V caps when the B+ is fairly low at 400V?
Any one have any information on the PS transformer, it's absolutely huge, part no, C512-14542-F. I need to know if it can power a second chassis. Here are some pictures. Also, check out how big that choke is, it's bigger than the output transformer.
The two speakers are 12 inchers. anyone have any idea what their impedance might be? It's gonna sound even better when I build a speaker cabinet. I'll use wood salvaged from the original organ body. The amp and premap/reverb chassis will be in a separate cab.
